Note.—Huber-White robust standard errors allowing for clustering of errors within state of birth/year of birth cells are in parentheses. More conservative Huber-White
robust standard errors allowing for clustering by state of birth to account for possible serial dependence in errors across cohorts within states are presented in brackets. The
race dummies are for African Americans and others. College graduates are those with 16 or more years of completed schooling; some college or more means 13 or more
years of completed schooling.
* The nonrestrictive birth control dummy variable equals one for individuals born in a state that, at the time the individual was 18 years old, had a nonrestrictive law
allowing minors (16 years and older) to receive birth control services and devices without parental consent. See table 2.
†
Equal to one for individuals born in a state that, at the time the individual was 17 years old, had a law allowing minors 17 years and younger access to birth control
without parental consent.
‡
Equal to one for individuals born in a state for which the earliest age to receive birth control without parental consent, for their birth cohort, was 18–20 years.
§
The legalized abortion dummy equals one if abortion was legal in the individual’s state of birth by the time the individual was 18 years old. In five states (Alaska, Calif.,
Hawaii, N.Y., and Wash.) abortion was legally available starting in 1970 (thus affecting cohorts born after 1951). In the other states, abortion was made legally available after
Roe v. Wade in 1973 (affecting cohorts born after 1954). On abortion laws, see Levine et al. (1996, table 1).

The average abortion rate (abortions/live births) in the individual’s state of birth when the individual was 18–21 years. Source: Donohue and Levitt (2001), with the
abortion information from annual survey data conducted by the Alan Guttmacher Institute. The abortion rate is assumed to be zero in each state prior to legalization.
